Port Moresby Jacksons International Airport lies in the tropics at 9.44° S, 147.22° E, on Pacific/Port_Moresby time (UTC+10). Tropical airports contend with heat and humidity, both of which thin the air and lengthen takeoff runs, and with convective storms that build fast in the afternoon.
Port Moresby Jacksons International Airport has 2 runways. The longest, 14L/32R, measures 9,022 ft by 148 ft, which puts the field in the widebody capable category: twin-aisle aircraft can use it, and narrowbodies have length to spare. The surface is asphalt. 1 of the 2 carry runway lighting.
Runway 14L/32R is aligned roughly south-east/north-west, which is the clearest hint you get about the prevailing wind here: runways are built to face the wind that blows most often, because aircraft take off and land into it. With 2 runways across 2 different headings, crews can pick whichever best suits the wind.
The runways are not interchangeable. 14R/32L is 4,625 ft against 14L/32R's 9,022 ft, a difference of 4,397 ft, so the shorter one generally takes regional traffic while the longer handles anything heavy.
